Joseph and NC, your both stars, so here's a beer each (_)3 (_)3,
in fact what the hell have two (_)3 (_)3, it's all doing what it should be
doing now :)

This simple site (ha ha ha ha) that I have been asked to do has turned into
a nightmare, in the past week I have had to get my head round more
JavaScript than
I have ever used, deal with tables of 300000 + records, and more complicated
MySQL statements than I though I would ever use.
Having said all that I have learnt a hell of a lot in the past few weeks :)

And now its nearly time to put it to bed and move on, notice how I slipped
in nearly......

One last question (well I hope last), I have a list of store number I was
going to use
a NOT IN statement, but worked out this is not going to work. What I am
trying
to do is, read in the store numbers and locations from the txt file and
create a strings like

$storenumberlist = '"SA002","SA003","SA004","SA005","SA006","SA007"';

$storenamelist = '"A Town","Big Town","Small town","The City","Corner
Shop","Another town"';

now run some sort of query and return a list of store numbers and store
location that DON'T appear in the table,
e.g. if SA007 was not in the table then return 'SA007' and 'Another town'
the trouble is I soon worked out that the NOT IN statement works the wrong
way round for what I need, and
the fact it can't return data thats not in the table, any ideas on how to do
this?

this is where I was heading, then worked out it was the wrong way

SELECT DISTINCT store, storename FROM $table_name WHERE (timestamp >=
$sdate) AND
(timestamp <= $edate) AND (store NOT IN ('$storenumberlist')) ORDER BY
store";

Looks like I may have to send you both a case of virtual beer :0

Brian
